SPECIFICATION forming part of Letters Patent No. 617,071, dated January3, 1899.

To all whom it may concern.-

Be it known that I, DIOKERSON G. BAKER, of lVillimantic, in the count-yof Windham and State of Connecticut, have invented a new and usefulImprovement in Machines for Winding Cops of Thread, of which thefollowing is a specification.

My invention relates to an improvement in machines for winding cops ofthread in which provision is made for successively winding cops or setsof cops upon a spindle and automatically ejecting the wound cops fromthe spindle as soon as they have reached the desired dimensions.

My invention contemplates in its broadest sense means for automaticallystarting the winding of cops of thread after the completion ofpreviously-wound cops by providing for automatically connecting with thespindle the threads which lead from the source of supply to thepreviously-wound cop.

My invention further contemplates means for automatically distributingthe power among independent sets of operating mechanisms.

A machine embodying the principles of my invention is herein shown anddescribed and is particularly adapted to the winding of what are termedsolid cops directly upon the winding-spindle as difi'erentiated from thewinding of bobbins on a hollow core, and I have shown in connectiontherewith a copejecting mechanism controlled by the wound cop or copsand so interrelated with the movement of the winding-spindle that themovement of the latter is interrupted, while the discharge of the woundcop or cops is effected and promptly resumed as soon as the dischargehas taken place.

In the accompanying drawings, Figure 1 is aview of the machine insideelevation. Fig. 2 is a top plan view. Fig. 3 is an end view looking fromthe left toward the right as the drawing is held in reading. Fig. 4 isan end view looking from the right toward the left as the drawing isheld in reading. Fig. 5 is a vertical transverse section on the line 5 5of Fig. 1. Fig. 6 is a top plan view of the mechanism for stopping andreleasing the shaft which drives the spindle and for starting andstopping the shaft which operates the ejector or discharge mechanism.Fig. 7 represents a reducing ear, forming a connection between thedrive-shaft and the spindlevertical longitudinal section through themachine.

The frame for supporting the working parts of the machine may be of anysuitable size and shape, as the particular conditions may require. Inthe present instance it is shown as consisting of a pair of heavy endstandards A A, connected by a bed-piece A The drive-shaft B is mountedin suitable bearings'in the uprights A A and is actuated by adrive-pulley b, fixed thereon, which is connected with a suitable sourceof power (not shown) by a belt I).

The drive-shaft B communicates a vibrating motion to the thread-guide bymeans of a cam-disk C, fixed thereon and provided with a slanting face0, Which bears against shoes d d, diametrically disposed upon the outerface of a yoke D, pivotally secured upon opposite sides of the shaft Bby pivots d to the sleeve (i mounted on the shaft B. The shoes d 01 maybe conveniently attached to the yoke D by inserting their shanks insplit sockets d d and clamping them therein by means of set-screws d also that they may be adjusted at diiferent distances from the center ofthe cam-disk C to vary the throw of the thread-guide or to suitcam-disks C of varying diameters.

The shank c of the thread-guide E is fixed in the top of the yoke D, andits upper edge may be provided with any desired number of slots 6 forthe reception of the threads leading from a suitable supply. (Notshown.) In the present instance the guide E is shown as provided withfive slots c and is adapted to simultaneously wind five cops on thespindle. It is obvious that a less number than five might be wound byleaving certain of the slots 6' out of use for the time being and that agreater number might be wound at the same time by introducing in theplace of the guide E a similar guide provided with more than five slots.The vibration of the guide E in the plane parallel with the axis of theshaft B will be made positive by the engagement of the cam U with theshoes at the diametrically opposite points of the yoke, since thethicker portion of the cam-disk will alternately come into contact withthe shoe upon the upper and lower sides of the said yoke.

The connection of the yoke D with the sleeve (Z while permitting thethread-guide to freely vibrate in one direction, is such as to cause thesleeve d to positively rock on the shaft B as the guide E is forced awayfrom the winding-spindle by the gradual increase in size of the copsbeing wound, and this rocking motion of the sleeve 01 is utilized forthe purpose of determining the point at which the winding of the copshall terminate by simultaneously effecting the stopping of the rotarymovement of the winding-spindle and setting in motion the ejectingmechanism for removing the cops from the spindle, as will hereinaftermore particularly appear.

The spindle-shaft is denoted by F. It is mounted in suitable hearings inthe standards A A and is driven from the shaft B by intermeshinggear-wheels f and b fixed, respectively, on the shafts F and B. Thespindle G, on which the cops are to be wound, is fixed at one end in theend of the shaft F, and its opposite end projects within a cop-receivingtube g, provided with a friction tongue or tongues g, projecting aslight distance from its interior surface along that portion of the tubeadjacent to the terminal point of the spindle G. The thread-guide E fordirecting the threads to the winding-spindle G is located between thereceiving end of the tube 9 and the base of the winding-spindle G, andthe spindle itself projects within the tube 9 a distance sufficient topermit a set of cops which may be simultaneously wound on the spindle tobe shifted along the spindle within the tube 9 without escaping from theend of the spindle while a new set of cops is being wound upon thespindle. It is to be understood that in speaking of a set of oops Iintend to include the winding of a single cop at any time in place of aplurality if for any cause it should be found preferable so to do. Fromwhat has hereinabove been stated it will be seen that the arrangement issuch that when a set of cops just wound is slid longitudinally along thespindle toward its free end within the tube g, by means of an ejectin gmechanism which will be hereinafter particularly described, it willforce a previous set of cops which has been temporarily permitted toremain on the spindle G, within the tube g, off the end of the spindleinto that portion of the cop-receiving tube g which is somewhatcontracted by the tongues g. This will hold the set of cops which hasbeen discharged from the spindle against a rotary movement, and theresult will be that the threads connecting the individual members of theset of cops which is held within the tube with the set of cops locatedon the spindle G, within the mouth of the tube, will be twisted offintermediate of the members of the two sets of cops, one held within thetube and the other rotating on the spindle, while a new set of cops isbeing wound on the spindle opposite the guide E.

The ejector consists of a depending arm 11, embracing at its lower endthe spindle Gand fixed at its upper end to alongitudinally-reciprocating bar h, mounted in suitable bearin s in theupper portions of the standards A A and operated by a depending stud h,preferably provided with an antifriction-roller, as is common, whichenters a cam-groove 7L2 in the face of a drum 71 fixed to rotate withthe sleeve h, mounted on a tubular box f, within which thespindle-shaftF rotates. The sleeve 72/4 has also fixed to rotatetherewith a wormwheel h, which is driven by a worm h on a vertical shaft727, the latter being provided with a worm-wheel h which is driven by aworm b on the sleeve 12*, mounted on a tubular box I), within which theshaft B rotates, and provided with a clutch member I), which engages aclutch member 12 on a sleeve 19 on the shaft B, and having fixed torotate therewith a drive-pulley b, adjacent to the drivepulley b,hereinbefore referred to. The sleeve Z2, carrying the clutch member I),is pressed toward the clutch member 12 by means of a spring b and theeffect of the spring-pressure upon the member b is regulated by means ofa tail-nut I), mounted on the screwthreaded end of the nipple Z2 whichsurrounds the sleeve b and is held in position by a clamping-plate I).As the tail-nut Z9 is turned in one direction on the nipple Z9 it willforce the clutch member 19 away from the member b against the tension ofthe spring b and as it is turned in the opposite direction it willpermit the spring 12 to exert a greater pressure upon the member 11 Itfol= lows, therefore, that when the drive-belt b is shifted from thedrive-pulley?) onto the drivepulley b the rotary movement of the sleeve19 imparted to the clutch members and to the sleeve 19 will rotate theworm b and hence the worm-wheel it and hence the worm h on the shaft hand hence the worm-wheel Won the sleeve h, carrying the drum 7L3, whichby its rotation will force the bar it, carrying the ejector, to thelimit of its advance stroke to crowd a set of cops into the mouth of thetube 9 and back again into normal position. (Shown in Fig. 1.)

The drive-belt is automatically shifted at the proper intervals from thedrive-pulley 6 onto the pulley b and back again onto the pulley b bymechanism under the control of the guide E, as follows: A drum K ismounted on the sleeve h, with one of its ends adjacent to the end of thedrum h and in the periphery of the drum K there is formed a camgroovefor the reception of a stud 70, projecting from the arm Z of abelt-shifting lever pivoted to a suitable support at L and having itsarm Z provided with a cross-head Z carrying a pair of studs or pins Z 1for e11- gaging the opposite edges of the belt I). The

drum K is held under spring tension tending to rotate it in a directionto shift the belt from the drive-pulleyb onto the drive-pulley b bymeans of a coil-spring k (see Fig. 5,) one end of said spring beingsecured to the sleeve M, which rotates with the drum h and the oppositeend to the drum K. The drum K is, however, prevented from rotating underthe tension of the spring 76, except at the de sired intervals, by meansof a catch I, fixed to rock with the sleeve (i to which the guide E isyoked, the nose 2' of said catch I (see Fig.

3) being adapted to engage a shoulder on a cam-disk 7c, fixed to rotatewith the drum K. The catch I is held against the periphery of the cam kand the guide E against the periphery of the cop being wound at thedesired pressure by a spring or weight, in the present instance by aspring R, connected with the end of an arm r, projecting from thesleeve, which carries the catch 1 and the guide.

From the above construction it follows that as the guide E is forcedaway from the spindle by the gradual increase in diameter of the copswhich are being wound it will rock the sleeve 01 and hence the catch I,gradually away from the cam-disk 71: until when the cop has reached thedesired diameter the nose iof the catch will escape from the shoulder I6and thereby set the drum K free to rotate under the tension of thespring. drum K rotates it will during its first halfrevolution rock thebelt-shifting lever in a direction to shift the belt from the pulley 1)onto the pulley b and the rotary movement of the drum K will betemporarily arrested at the limit of such half-revolution to hold thebelt for a time upon the pulley b by means of the engagement of a lug kon the periphery of the drum K, adjacent to the end of the drum with thenose on of a springactuated dog M pivoted to a suitable support at m.(See Fig. 5.) The said drum K will be again released and permitted tocomplete its revolution under the tension of the spring 70 when the drum7L nears the completion of its revolution by the engagement of a lug iton its periphery adjacent to the end of the drum K with the nose on ofthe dog M. The outer end of thelug 70 is rounded, so that it will notcatch the nose of the dog, but will pass beneath it and gradually liftit back out of engagement with the lug k on the drum K. It is obviousthat that portion of the nose m of the dog M which is opposite the lug kon the drum 72 might be rounded and the lug 79 left squared, if suchreversal were found desirable. lVhen the drum K is so released by therotary movement of the drum 72. it will complete its secondhalf-revolution and in so doing will rock the lever L into the positionshown in Fig. 1 to shift the belt back again from the pulley 5 onto thepulley b, and thus will again start the rotary movement of the spindle.Since the aotuating-spring7t is secured at one end As the to the sleeveh, which rotates together with the drum h the rotary movement of saiddrum 7L3 will serve to wind the spring and keep it wound, so that it isat all times ready for action to turn the drum K. The drive-pulleys band b are promptly brought to a stop, when the belt is releasedtherefrom, by means of brakes S and S, which are slid toward the facesof the pulleys by the inclined ends of the belt-shifting pins Z Z withthe beveled ends 3 s of the sliding brakes S S as the belt-shiftinglever is rocked back and forth. The sliding brakes S S are promptlythrown out of engagement with their respective pulleys when released bythe belt-shifting pins or studs Z 1 by the frictional engagement of theface of the pulley with the brake, tending to slide it away from itsface. The relation of the belt-shifter to the brakes is clearly shown inthe detail plan view, Fig 6. The tension device for holding the severalthreads under the proper strain as they are fed to the windingspindle ishere shown as consisting of a series of glass or other highly-polisheddisks 0, held pressed toward one another by a spring 0, the tension ofwhich may be increased or diminished at pleasure by means of a thumb-nutP.

To keep the face of the cam-disk C properly lubricated along the pathwhere it bears against the shoes upon the yoke which carries the guideE, I find it convenient to provide a stick of graphite or other suitablelubricating material Q, supported in a suitable socket q, projectingfrom the standard and pressed gently against the face of the disk by aspring q within the socket.

The intermeshing gears f and b may be relatively varied at pleasure tomake the number of rotations of the spindle correspond to or vary fromthe number of Vibratory movements of the guide E as may be founddesirable. In the form shown in Fig. 7 provision is made for driving thespindle-shaftF a little slower than the drive-shaft B by making thegear-Wheel'F corresponding to the gear-wheel f in Fig. 1 a littlesmaller than the gear-wheel 13 corresponding to the gear 12 in Fig. 1.This will make the vibratory movement of the guide E and the rotarymovement of the spindle non-synchronous, so that the diagonal positionof the thread across the periphery of the cop being wound will vary itsposition during the successive rotations of the cop and add to itsfirmness.

The operation of the several parts of the machine have been so fully setforth in connection with the foregoing description. that a furtherdetailed statement of the operation is not deemed necessary. Theoperation may, however, be concisely stated as follows: As soon as theset of cops has been wound on the spindle G of sufficient size to pressthe guide E back to a point where the catch I will release the disk Itand hence the drum K, the latter will complete a half-revolution andshift the belt from the pulley l) to the pulley b and thereby start therotary movement of the sleeve b and hence the rotary movement of thedrum h3 by the intermediate connection of worm-wheels and worms. Therotary movement of the drum its will advance the ejector II and slidethe set of cops already wound into the end of the tube g. As the drum77, nears the completion of its revolution it will set free the drum K,which has already been arrested at a half-revolution by thespring-actuated dog M, and the said drum K will complete its revolutionunder the tension of its actuatingspring and will again shift the beltfrom the pulley b onto the pulley b and hence start the winding of a newset of cops. The drum K will be arrested at the completion of itsrevolution by means of the catch I, the nose of which will catch overthe shoulder as clearly shown in Fig. 3. As the second set of cops isslid along the spindle G by the ejector II it will crowd the setpreviously wound off the spindle into the contracted portion of the tubeG, where they will be held against a rotary movement, while the rotarymovement of the set subsequently wound during the winding of asucceeding set will twist apart the threads which unite the members ofthe discharged set of cops with the members of the set on the spindlewithin the end of the tube. In this manner the machine willautomatically proceed to Wind set after set, eject them from thespindle, and sever the threads which connect them with those which havebeen previously wound.

It will be observed that by throwing apart the clutch members whichconnect the sleeves for transmitting motion from the drive-pulley b tothe ejecting mechanism, the belt being at the time on the drive-pulley bthe sleevesection which carries the pulley b will be permitted to rotateidly and the operation of the machine will be stopped without stoppingthe drive-belt b.
